Issue with OnBeforeDrawChart

Hello, I need to have the plot area (area between axes) painted in white so I added some code in the OnBeforeDrawChart event. When I start the app the area inside the plot is painted with the default colour and once I move the mouse inside the event code executes well. Is there a way to fix this? I ...

Re: General question about antialias drawing

I maybe mistaken but from what I read there is no way to have only the Series plotted antialised, axes always get affected.

Re: Point series and marks text position

Hello Yeray, I try to create a band between 2 PointSeries, for each PointSeries I create LineSeries that is a smoothing function of the associated PointSeries.

Point series and marks text position

Hello, I am using the latest TChart version and I have trouble to adjust marks text placement when YMandatory is set to false. If I set YMantatory to true then then I can control the margin between the mark point and text by adjusting the arrow length. How can I adjust the text position and what exa...

General question about antialias drawing

Hello,

Is it possible to draw a FastLine series in antialised mode without having to enable antialias for the whole chart object? I investigate if there is a way to have the antialias effect enabled only on my line series

Fill area between 2 series

Hello, I believe this question was asked many years ago but I could not retrieve anything from Search. I need to fill the area between 2 series (e.g. Series1 and Series2) with a constraint that fill will apply only when Series1 values are smaller than Series 2 (see attached image), I tried using the...

After upgrading to Rio I found myself struggling with various issues with the latest TChart version. For the past couple of days I am trying to figure out why the labels of point series do not display correctly, it appears that some random numbers are added (see attached image). The line of code I u...

Re: Issue with bar chart

The issue appears to be solved if I set Sort -> Y -> Ascending instead of Sort -> None but I need to have the values list unsorted
